iPhone 3G firmware has FM radio support, FOTA

Reports from users in possession of the latest iPhone 3G firmware indicate that the device will have support for both FM radio and FOTA (firmware over the air).

FM radio support means that the iPhone 3G may be able to make use of devices like Apple's own "iPod Radio Remote," which includes an FM tuner and allows users to listen to FM radio stations. Current iPhone and iPod touch models are incompatible with the radio remote.

Firmware over the air support means that Apple will theoretically be able to deliver software and firmware updates over the iPhone's cellular network connection, potentially allowing re-locking of unlocked devices and feature enhancements that do not require connection to a host computer.
